Notes support the ntfs ADS (Alternative Data Streams) while opening and saving attachments

The feature It is possible, that notes recognizes the source of the file (e.g. mail from an internet sender = not trusted, ADS (Alternative Data Streams)sets flag not trusted so office/pdf etc. open it read only // internal sender = trusted, ADS sets flag trusted so office/pdf opens it normal etc.).

We want to use ADS to tell the programs, while/after an attachment was detached or opened from the notes client, what to to with it, so not really who have access to the file, but rather which security level is to realize. E.g. when I download a file from the internet with firefox, ADS tells the progams e.g. Office, to open it in read only mode first.
